'Neebe, W o odbu1-y, N J I h I Q V applicationhugust va, 1935, Serial No. 34,586 I This invention relates generally to an improved waist bearer. for locomotives of the Mallet articulated type, and it "is one object of my present invention to provide-a compact, simple, safe and sturdy waist bearer cross-tiewhich will functionwithout the necessary complications involved in various'priorart arrangements.

A further object is to provide improved wearing strips, and'means whereby they may beeffectively and easi y lubricated together with ease of renewal.

Other objects and advantages will be more apparent to those skilledfollowing description. of the accompanying drawings in which:

In the particular'embodiment of the invention which is shown hereinmerely for the purpose of illustrating one specific form among possible others that the invention=might take in practice, I have shown in Fig. 1 a Malletarticulated type of locomotive having a boiler I attached rigidly to the rear frame2 at'points adjacent the rear cylinders 3 and firebox 4. A forward frame 5 is pivotally connected asat- 6 to. the rear'frame 2. A forward portion of the boiler-l is supported upon frame5 through a waist bearer and cross tie generally indicated at 1. It .will of course be understood that each ofthe frames 2 and 5 is provided with usual running gear. actuated respectively from the rear cylinders 3 and-front cylinders 8. Inasmuchas the structure of such devices iswell-known, it is not necessary to describe the same here. 4

The waist bearer is 'supportedu'ponthe cross tie structure generally indicated atlO. .The cross tie has; as shown in Fig. 3; a horizontal webl-2 whose longitudinal edgesare provided w'ithangledflanges I; which iii.

as shown in. Fig. 2-terminate longitudinally at a recess 14.1 The-horizontal portion of flanges l3 rests upon the locomotive frame 5 which as shown in Fig. 3 is specifically 'of the bar type.- A usual depending lug l5 projects downwardly. between the two sides of the bar fra'meand is secured thereto in any usual manner.: Itrwill be noted from Fig. 2 that there are-jtwoi such lugs;.l5 flanges IE to provide an extremely strong and yet compact cross tie, and I have provided.- a steam-pipe conduit l1 so arrangedthat the horizontal web l2 intersects sit the wall of conduit l1, therebyobtaining a high degree of structural cooperation .betweenfthese two elements so that they mutually directly,- re- 1 inforce each other. The steampipe I1: as shown in Fig. 2 is ofsuch shape. as to permit various connecting pipes to be properly secured thereto.

Snugly 5,: thereby insuring element 25 as f disposed within theelongated recess formed between flanges 2fi-iandzg2l .is a wearing plate. 28 having a concave'bearing-surface 29, relatively large fiat wearing plate-.Bilfis providedfon its under side. adapted to he to the concave greater length seated within and complementary seat 29.. The bearing strip 28 is of than ther fiangesflfi thereby extending to the opposite ends of member'25. The bearing plate 30,-=however,"is only;of the same length as flanges 26. Projections '32 are formed integrally with the opposite ends. of plate 39 so as toform continuations ofathe convex surface;3l, the total length of such surface 3| being with a convex bearing surface 3| the same as that of plate 28. Hence the ends of members 25, 28 and 32 will be substantially plane. Nortransverse web is in I It will of course; be fforegoing elements of cast as an integral mally these plates are nested together as shown in Fig. 2 and are held in such relation by locking yokes at each end thereof. One such locking yoke is shown at 33 and has an opening 34 of such configuration as to permit the yoke to be slipped over the end 21, plate 28 and projection 32 as shown in Fig. 2. This yoke is then welded to member at any suitable points. It will be understood, however, that the opening 34 is of such size that plate is permittedto-rockon the convex-concave surfaces 29 and 3|. 1

Interposed between plate 30 and the flat surface 36 of waist bearer plates 31 and 38. One or both of these plates are provided with a suitable oil recess 39 which may be supplied from oil reservoirs 40. reservoirs are formed in a laterally recessed por:

tion of the waist bearer and may be provided with a reservoir of upstanding flanges 4| to form I ample capacity from which the oil is fed to recess 39 through openings 42, Fig. 3. To insure that the bearing strips and "boilerare maintained together at all times, the waistbearer as shown in Figs. 2 and 3 has centrally located depending hooks 43 extending downwardly and under p1ate'30. Thus it is seen that the boiler and cross tie l0 can have relative-rocking movement between the surfaces Hand 31 as well as lateral sliding movement between thebearing plates 31 and 38 thus accommodating all movements of the boiler and cross tie. 1 To insure maximum stability of the supporting box 19 and rigidity of the cross tie as a whole, I employ a longitudinallyextending vertical web 44, Figs. 2 and 3, one adjacent each side of-the locomotive bar frame, while substantial longitudinal c-ontinuations of these webs. are indicated at in Fig. 2. It will be noted that the combined webs 44 and 45 are of substantially arch formation and terminate at their forward ends in amain vertical transversely extending web 41. This turn reinforced on its front side by horizontal ribs 48 and 49. The web is thus adapted to' effectively function to provide as shown in Fig. 4 vertical pads-50 for suitable valve gear link bearings while brake cylinder pads 51' may be formed in effective supportingrelation to the upper rib 48. The front web 41 alsospermits an effective support 53, Fig. 2, fora counterbalance springof a reverse shaft while horizontally extending guide lugs-54 are formed-in reinforcing relation tofvertical web 41. and lower ribs 49. A similar mutual reinforcing relation is obtained asshown in Figs. 2 and 4 between brake hanger brackets 56 and the upper one of flanges l6 and the longitudinal arched web 44.

understood that all of the the cross tie are preferably unit whereby the foregoing mutual supporting relation-between the elements is obtained in a very effective manner. This construction is of course highly beneficial'in insuring a very 'stablesupp-ort for the improved hearing plates 28 and 30=wherebythe same may efficiently maintain complete'operative relation between the boiler and the cross tie.

It will of course be understood that various changes in details of construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of the invention as set forthin the appended claims.
